We know that fad diets do have their benefits, but it’s not something you should stick to for a long time. The side-effects of a lopsided (or uninformed) diet choice may have serious long-term consequences. Try them in bits and spurs (Paleo week, anyone) by consulting with your nutritionists and you will have better results.

Speaking of results, one of the consequences of a high-protein Paleo diet, especially in obese and overweight middle-aged adults trying to lose weight, is better sleep. That’s what a new study from Purdue University says. Admittedly the group behind the research is largely made of associations with a vested interest in protein consumption. Purdue University’s study was funded by National Dairy Council, National Institutes of Health, Beef Checkoff, National Pork Board and Purdue Ingestive Behavior Research Center.

“Most research looks at the effects of sleep on diet and weight control, and our research flipped that question to ask what are the effects of weight loss and diet — specifically the amount of protein – on sleep,” Dr Wayne Campbell, nutrition science professor was quoted as saying in this report.

He added that the quality of sleep improves for those middle-aged adults consuming lower calorie intake and having high-protein diet as compared to those adults who lost the same weight but consumed a normal protein diet.

A pilot study with 14 participants studied effects of consuming more dietary protein. It concluded that subjects had better sleep after four weeks of weight loss. 44 overweight or obese participants were then entered into the main study with two groups – one that consumes a normal-protein and another that eats a higher-protein weight loss diet. After a brief silent period for adapting, the two groups consumed either 0.8 or 1.5 kilograms of protein daily for each kilo of their body weight for 16 weeks.

Then in a survey to determine quality of sleep, those who consumed the high-protein diet while losing weight reported better and longer sleep patterns. “Short sleep duration and compromised sleep quality frequently lead to metabolic and cardiovascular diseases and premature death,” Jing Zhou, a doctoral student and the first author, was quoted as saying.
